The objective of our study was to determine if there are differences between the light power in a led lamp with the contaminated filter and a led lamp with the non-contaminated filter used in offices in the city of Iquitos in 2019. The sample consisted of 153 led lamps, the study was quantitative, correlational descriptive cross section and the following results were obtained: The most used brand was the Woodpecker with 60.8%. (93), followed by other brands with 33.3% (51), the Ivoclar, 3M and Gnatus brands were only 2% of the sample (3 each). In relation to the time of use at the time of the study, 35.9% (55) were being used more than three years, 19% (29) 2 years, 15.7% (24) less than 6 months, 13.1% (20) more than 2 years, 8.5 %% (13) 1 year, 5.9% (09) more than 1 year and 2% (03) more than 6 months. Regarding the frequency of use of led lamps at the time of obtaining the results, 28.8% (44) were used daily, 28.1% (43) were used weekly, 17% (26) was used biweekly,, the 12.4% (19) was used monthly, 11.8% (18) was used interdiarily and 2% (3) quarterly. It was determined that the LED lamps were used with the following light curing times: 78.4% (120) 20 seconds, 7.2% (11) 40 seconds, 4.6% (07) 5 seconds, 3.9% (06) 30 seconds , 2.6% (04) 10 seconds, 2% (03) 15 seconds and 1.3 (02) 25 seconds. 94.1% (144) has a filter length of 5 cm, 5.2% (08) other lengths and 0.7% (01) 10 cm. 42.5% (65) of LED lamps belong to the private sector, 57.5% (88) to the state sector. 49% (75) of the led lamps were cleaned before use and 51% (78) was not cleaned before use. 94.7% (71) of the lamps cleaned before use used alcohol and 5.3% (04) another type of solvent. 91.5% (140) did not use protection barrier for its use and 8.5% (13) did use protection barrier before use. It was determined that 90.8% (139) of LED lamps with a contaminated filter have a recommended power (> 400 mw / cm2) and 9.2% (14) do not have the recommended power (<400 mw / cm2), it was also determined that 91.5% (140) of LED lamps with a non-contaminated filter have a recommended power (> 400 mw / cm2) and 8.5% (13) does not have a recommended power (<400 mw / cm2), therefore it could be determined if there is a relationship between the light power of the LED lamps with a contaminated and uncontaminated filter, obtaining a value of p = 0.0000 (p> 0.05).
